The pressures on one of the world’s most famous centres of biodiversity, the Galapagos Islands where Darwin studied his famous finches which contributed to the theory of evolution, have been highlighted by Ecuador’s President and Unesco, the UN’s scientific and cultural body. The president of Ecuador, Rafael Correa, has warned that he is considering a temporary suspension of tourist permits to the heavily-visited Galapagos islands and enforcing rigorous population restrictions to prevent further environmental harm. Tourism and fishing are both bringing massive pressure on the fragile islands.

"We are pushing for a series of actions to overcome the huge institutional, environmental and social crisis in the islands," said Correa after signing an emergency decree on tuesday April 10.

Mr Correa called on his cabinet and local authorities to meet urgently to find ways of better preserving the country’s most popular tourist destination. He did not provide any details about the possible restrictions, but said the country would consider suspending some tourism permits.

The director of UNESCO’s World Heritage Center warned last month of the threats to the flora and fauna of the “fragile and delicate” volcanic island chain.

A United Nations delegation is visiting the islands to determine whether the World Heritage site should be officially declared “in danger”.

Professor Richard Keynes, the retired emeritus professor of physiology at Cambridge University, UK, and great-grandson of Charles Darwin, said tourism is interfering with the ecological life on the archipelago.

"The Galapagos are in danger of being overoccupied by tourists and for a long time I have been worried about it. The number of visitors used to be under control and they could only land when conservationists were with them. Now there are so many tourists that they want to land a thousand people at a time and you simply cannot do that without destroying the islands.

"The president is right to control numbers. They will not make money if they lose the islands."

John Harris, the executive director of the Galapagos Conservation Trust, said the recent growth in tourist numbers was a major concern.

"They have a wildlife that is untouched by the outside world, but the outside world is coming to them. It is a special experience, but by visiting them, you destroy them. People live there only because of the tourism."

In the mid 1970s tourism to the Galapogos was a trickle with no more than 7,000 visiting the islands annually. But last year 120,000 tourists visited the Galapagos, up from 40,000 in 1991. Numbers are rising at an annual rate of 12 per cent, fuelling new building on the islands to accommodate them. Over-fishing is also blamed for putting some marine species at risk.

Fishing and tourism are the two mainstays of the Galapagos economy, and the money they produce has led to an influx of people from the Ecuadoran mainland. The official population of the 13 main and six smaller islands is around 18,000 people, but an additional 15,000 people are believed to be present illegally.

Immigrants and tourists have led to rising pollution and an increase in invasive species. There are now 748 species of introduced plants compared to the 500 species of native plants.

"The national park does an incredible job, but if the population continues to grow, the greater the possibility of new species being introduced to the islands and the greater the human footprint," says Lauren Spurrier, managing director of the World Wildlife Fund’s Galapagos program.

Officials in 1998 limited the number of tour boats allowed in the waters around the islands to about 90 licensed craft, but tour companies have decreased the average length of tours, allowing more tourists to visit. Since last year, larger tourist ships have also been allowed into the islands to meet tourism demand. And with 36 Boeing 737 flights arriving on the islands every week, there are plans to open a new airport.

Given the economic importance of tourism, it is highly unlikely that tourism would be even temporarily banned by the government, despite a spokesman for the Tourism Ministry warning that the government might suspend tourism permits "until scientific studies see exactly how much the capacity of the islands can withstand without too much impact". Indeed, banning tourism may do more harm than good, throwing many thousands of people out of work and carrying the risk of increasing illegal fishing as the only other way of earning a living.

Placing an economic value on wildlife is often the best way of protecting it. In parts of Africa, for example, endangered animal species and fragile ecosystems have survived precisely because they have value as tourist attractions. In the Galapagos, illegal fishing for shark fin soup threatens the shark population, but tourism at least gives an economic incentive to protect sharks and other animals. The dilemma, however, is that tourism also encourages illegal immigation by people from the economically deprived mainland, and stronger action needs to be taken to control this. Strict limits on tourism also need to be maintained and codes of behaviour rigorously enforced, to try and protect the ecosystem and make tourism sustainable. Otherwise, the famous wildlife may be on borrowed time.

    Thank you. As a resident/Colonial Permanente of San Cristobal, Galapagos I would like to add some points. #1 The major reason we are at the cross roads we are today is that we’ve had eight presidents in ten years, the majority of which have been “business” friendly and corrupt. This allowed much of the illegal immigration. Also the fishermen hold a big block of votes which has stymied intelligent fishing regulations, add to that the goverment by restricting the ways they can use their licenses has failed to provided them with alternative sources of income. We now have a president who appears to have a good chance to remain in power for his four year term. I have personally been invited and attented conferences held by the new administer of tourism, agriculture and economics. The national park has been doing research and a man from the Charles Darwin foundation came by the house to talk for a few hours the other day. The original idea of keeping the tourists on boats was a good one when there were only a few boats. Now there are more than a hundred boats which leave their trash on the islands, pump raw sewage into the ocean, rip the reefs up with their anchors, burn fossil fuels twenty-four seven, employee workers and purchase produce almost exclusively from the mainland and the majority of these are owned by people who have no connection to the islands except as a place to make money. Please, if you know anyone wanting to visit the Galapagos, ask them to do it as part of the solution, not as part of the problem. Please check out

    We need to protect our wonderful site of the planet
